PROBLEM TO BE SOLVED: To obtain a flame-retardant resin compsn. which has a high flame retardance and excellent mechanical properties by compounding a thermoplastic resin with specified amts. of a bromine flame retardant and a free radical generator and thereby promoting the dripping during burning. SOLUTION: This compsn. is prepd. by compounding 100 pts.wt. thermoplastic resin (pref. a polyester resin, a polyamide resin, or a styrenic resin) with 0.1-30 pts.wt. bromine flame retardant pref. comprising at least one compd. selected from among a brominated PS, a brominated polyphenylene ether, and a brominated polycarbonate and 0.01-10 pts.wt. free radical generator pref. having at least either an -O-O- bond or a -C-C- bond and/or having a 1-min half-life temp. of 200 deg.C or higher. Pref., the free radical generator is a compd. of formula I, pref. formula II, still pref. formula III, or a compd. of formula IV. In the formulas, R<1> to R<9> are each H or a 1-10C monovalent org. residue provided R<7> to R<9> may be substd. by at least one -OOH group. |
